Peter Gibson, a spokesman for Keep Britain Tidy, asserts that Banksy's work is simple vandalism,[198] and Diane Shakespeare, an official for the same organisation, was quoted as saying: "We are concerned that Banksy's street art glorifies what is essentially vandalism."[55] In his column for The Guardian, satirist Charlie Brooker wrote of Banksy "...his work looks dazzlingly clever to idiots."[199]

Banksy started as a freehand graffiti artist in 1990–1994[30] as one of Bristol's DryBreadZ Crew (DBZ), with two other artists known as Kato and Tes.[31] He was inspired by local artists and his work was part of the larger Bristol underground scene with Nick Walker, Inkie and 3D.[32][33] During this time he met Bristol photographer Steve Lazarides, who began selling Banksy's work, later becoming his agent.[34] By 2000 he had turned to the art of stencilling after realising how much less time it took to complete a work. He claims he changed to stencilling while hiding from the police under a rubbish lorry, when he noticed the stencilled serial number[35] and by employing this technique, he soon became more widely noticed for his art around Bristol and London.[35] He was the goalkeeper for the Easton Cowboys and Cowgirls football team in the 1990s, and toured with the club to Mexico in 2001.[36] Banksy's first known large wall mural was The Mild Mild West painted in 1997 to cover advertising of a former solicitors' office on Stokes Croft in Bristol. It depicts a teddy bear lobbing a Molotov cocktail at three riot police.[37]

The Borderline Mural Project covers a 200 foot long wall in the tunnels under the campus of MIT with murals and magic. The tunnel is a commonly used route between MIT Buildings 66 and E17 during bad weather. A useful connection between point A to point B, Borderline aims to make the tunnels a destination. The magic comes in the form of augmented reality: viewers can use the Artvive mobile phone app to experience an extension of the imagery.

It was reported that then-New York City Mayor Michael Bloomberg called Banksy a vandal whose work is not the definition of art, and that the NYPD's vandal squad was on the hunt for Banksy over his various graffiti art and installations.[114][115][116] One creation was a fiberglass sculpture of Ronald McDonald and a real person, barefoot and in ragged clothes, shining the oversized shoes of Ronald McDonald. The sculpture was unveiled in Queens but moved outside a different McDonald's around the city every day.[117][118][119] Other works included a YouTube video showing what appears to be footage of jihadist militants shooting down an animated Dumbo; travelling installations that toured the city including a slaughterhouse delivery truck full of stuffed animals and a waterfall; and a modified painting donated to a charity shop which was later sold in an online auction for $615,000.[120][121] Banksy also posted a mock-up of a New York Times op-ed attacking the design of the One World Trade Center after the Times rejected his submission.[122][123] The residency in New York concluded on 31 October 2013;[120][124] many of the pieces, though, were either vandalised, removed or stolen.[125]

On 18 February, BBC News reported that a recent Banksy mural, known as the Slave Labour mural portraying a young child sewing Union Flag bunting (created around the time of the Diamond Jubilee of Elizabeth II) had been removed from the side of a Poundland store in Wood Green, north London, and soon appeared for sale in Fine Art Auctions Miami's catalogue (a US auction site based in Florida). News of this has reportedly caused "lots of anger" in the local community and is considered by some to be a theft. Fine Art Auctions Miami has rejected claims of theft, saying it had signed a contract with a "well-known collector" and that "everything was above board"; despite this, the local Councillor for Wood Green is campaigning for the work's return.[105]

Banksy opened Dismaland, a large scale group show modelled on Disneyland on 21 August 2015. It lampooned the many disappointing temporary themed attractions in the UK at the time. Dismaland permanently closed on 27 September 2015. The "theme park" was located in Weston-super-Mare, United Kingdom.[127][128] According to the Dismaland website, artists represented on the show include Damien Hirst and Jenny Holzer.[129]

Many works that make up the Better Out Than In series in New York City have been defaced, some just hours after the piece was unveiled.[185][186] At least one defacement was identified as done by a competing artist, OMAR NYC, who spray-painted over Banksy's red mylar balloon piece in Red Hook.[187] OMAR NYC also defaced some of Banksy's work in May 2010.[188][189]
If anyone supposes they have a sense of humor and a little bit of irreverence, or is it reverence, for the human condition.... this book will sure to make that anyone a banksy fan. As you flip through the pages you might find yourself claiming each work as your favorite. I highly recommend watching his movie too. It feels to be a continuation of the story he tells... right when you were wishing you had a banksy piece on your wall he throws you a curve ball.. hilarious. It's not a race!

In March 2010, the work Forgive Us Our Trespassing was displayed at the London Bridge in conjunction with Art Below an arts company that put on art shows on the London Underground. The work was censored by the Transport for London (TfL), forbidding display of the work with its halo, because of the prevalence of graffiti in the underground.[87] It was displayed without the halo over the boy's head, but after a few days the halo was repainted by a graffitist, so the TfL disposed of the poster. This decline went through the press and several articles were published remarking on the progress of the poster.[87][88]

In October 2018, one of Banksy's works, Balloon Girl, was sold in an auction at Sotheby's in London for £1.04m. However, shortly after the gavel dropped and it was sold, an alarm sounded inside of the picture frame and the canvas passed through a shredder hidden within the frame, partially shredding the picture.[134] Banksy then posted an image of the shredding on Instagram captioned "Going, going, gone...".[135] After the sale, the auction house acknowledged that the self-destruction of the work was a prank by the artist.[136] The prank received wide news coverage around the world, with one newspaper stating that it was "quite possibly the biggest prank in art history."[134] Joey Syer, co-founder of an online platform facilitating art dealer sales,[137] told the Evening Standard: "The auction result will only propel this further and given the media attention this stunt has received, the lucky buyer would see a great return on the £1.02M they paid last night, this is now part of art history in its shredded state and we'd estimate Banksy has added at a minimum 50% to its value, possibly as high as being worth £2m+."[138] A man seen filming the shredding of the picture during its auction has been suggested to be Banksy.[139][140] Banksy has since released a video on how the shredder was installed into the frame and the shredding of the picture, explaining that he had surreptitiously fitted the painting with the shredder a few years previously, in case it ever went up for auction. To explain his rationale for destroying his own artwork, Banksy quoted Picasso: "The urge to destroy is also a creative urge".[141][142] (Although Banksy cited Picasso, this quote is usually attributed to Mikhail Bakunin.) [143] It is not known how the shredder was activated.[144] Banksy has released another video indicating that the painting was intended to be shredded completely. The video shows a sample painting completely shredded by the frame and says: "In rehearsals it worked every time...".[145]
